Windows Azure SDK Refresh released

I noticed it a little late, but Microsoft released a refresh of the Windows Azure November 2010 SDK(1.3). I still want to mention it because it solves a security issue with the Windows Azure Software Development Kit (SDK).  I strongly encourage you to install the refresh of the SDK and redeploy your application(s).

Who is affected?

This issue affects applications developed using ASP.NET and using the new "Full IIS" feature of SDK v1.3 that have a Web Role deployed.

In particular, this affects web sites and services that use cookies to maintain state information either within a session or between sessions (if interactions in one session can affect what happens in a subsequent session). These cookies are cryptographically protected so that clients can see that there is state information being passed but cannot see the contents of that state information and cannot change it. In the case of vulnerable Web Roles, it may be possible for clients to determine the contents of the state information (though the client could still not change it). If the web site depended on the client not being able to see the contents, its security could be compromised.

Applying the fix

To apply the fix:

1.     Download and install the refresh of the November 2010 Tools and SDK (recommended).

2.     To upgrade just the SDK, use this link (64 bit) or this link (32 bit)

After you've applied the fix, you'll have to re-package your service and then upgrade or re-deploy your service in the cloud.

Verifying the fix

To verify the fix has been applied:

1.     Check the version number of 'Windows Azure SDK' after upgrading to this refresh, as displayed under 'Programs and Features.' It should be 1.3.20121.1237.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

.NET 9 - Goodbye sln!

Although the csproj file evolved and simplified a lot over time, the Visual Studio solution file (.sln) remained an ugly file format full of magic GUIDs. With the latest .NET 9 SDK(9.0.200), we finally got an alternative; a new XML-based solution file(.slnx) got introduced in preview. So say goodbye to this ugly sln file: And meet his better looking slnx brother instead: To use this feature we first have to enable it: Go to Tools -> Options -> Environment -> Preview Features Check the checkbox next to Use Solution File Persistence Model Now we can migrate an existing sln file to slnx using the following command: dotnet sln migrate AICalculator.sln .slnx file D:\Projects\Test\AICalculator\AICalculator.slnx generated. Or create a new Visual Studio solution using the slnx format: dotnet new sln --format slnx The template "Solution File" was created successfully. The new format is not yet recognized by VSCode but it does work in Jetbr...
